Re: Simple Custom Video Dashboard 30+ FPS

I wonder why that is if it's the case - couldn't we decouple the two and have new pictures sent to the dashboard as quickly as possible while doing the image processing in a parallel loop? I'm going to post the question for the NI guys because I don't see any obvious reasons it wouldn't work.
I've gotten 30 fps running on TheDominis's dashboard on a laptop besides the Classmate. The entire reason the FPS is slow low is because the Classmate's processor is too slow to handle the image processing any faster. The bottleneck is not in the cRIO, but the Classmate.

I'm developing my own video display (using C++ instead of a .NET language) with some hardware acceleration (Direct3D 9). I'll let you know if there's any speed increase.
